The above numbers are for circuit length estimation only. For more detailed information please use the Pentair TraceCalc software or contact your local Pentair representative. Pentair requires the use of a 30 mA residual current device to provide maximum safety and protection from ï¬Âre.
Where design results in higher leakage current, the preferred trip level for adjustable devices is 30 mA above any inherent capacitive leakage characteristic of the heater as speciï¬Âed by the trace heater supplier or alternatively, the next common available trip level for non adjustable devices, with a maximum of 300 mA. All safety aspects need to be proven.
